Subject line says it all - it has been happening intermittently since I removed my obsolete Sonos Bridge, and recently has become more frequent and frustrating. The media library is on a WD MyCloud NAS hardwired into the home network. The MyCloud DLNA Media Server is ON - but seems to ‘see’ way more attached Sonos media players than I actually have....
One of the Sonos speakers (Sub) is hardwired into the network ( did this to fix the problem whereby the system was occasionally losing rooms / speakers): the other speakers are connected via wifi. DHCP is dynamic.
I tried fixing this by rebooting the wireless hub (SmartRG SR505N) with no luck this time. The NAS is up and running fine: I can connect to it from my iMac, and the library is there. I will happily submit diagnostics if you tell me what to do.
I used to love this system, but it is getting harder to love …… It should not be this hard …..
